I cant seem to open feddit.nl through this instance, a community i wanted to subscribe to. I cant seem to find a link to that community in the communities tab when searching for all, and when typing it in the browser i get a 404. Does every instance have to manually link every instance or something? Or am i using it wrong?
You get a 404 because the other communities haven’t been added to your instance yet. To make communities and posts from other instances visible, someone has to manually add them first. You can do this by heading over to feddit.nl, taking the link of any community you wish to add, and then pasting that link into the search bar of your home instance. At that point the community should finally appear and you can subscribe to it. Hope this helped!
Notably, it can take a minute or two sometimes. It’s a bit of a process to get groups federating the first time. I’m hoping that improving group discovery is prioritised by the devs some time soon
